ADJUSTING MECHANISM FOR PLOW-BEAIJIS.

Serial No. 513,388.

To all whom it may concern:

Be it known that I, \VILLIAM L. BEALL, citizen of the United States, residing at Albion, in the county of Calhoun and State of Michigan. have invented certain new and useful Improvements in Adjusting Mechanism for Plow-Beams; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to the construction of plows and more particularly to plows in which an iron or steel beam is employed, and consists in an improved means for adjusting the beam to regulate the width of the furrow or to change the position of the plow with respect to the point of draft.

The principal parts of the plow shown in the drawings are a land side 1 and a share 2 brought together and secured to a frog 3, pressed or drop forged into the proper form to receive the other parts. The beam A is also secured to this frog in this instance by bolts a, a one at least passing through the land side, frog and beam. They may pass through the frog and beam alone but by having one or more passing through the land side act to secure the land side and frog together. In this construction it will be seen that the beam is secured to the plow parts within the hollow of the plow or in rear of the main earth engaging surfaces.

It is often desirable to adjust the plow for varying width of cut or to properly aline it in respect to the point of draft. For instance, in using three horses the point of draft is farther from the land edge of the previous furrow than when two horses are employed to draw the plow. It is found desirable to adjust the plow to these and other changing conditions by varying the position of the beam.

In the accompanying drawings I have illustrated the best form in which I have contemplated embodying my said invention and the said invention is disclosed in the following description and claims.

In the said drawings, Figure 1 is a top or plan view of a plow, one adjustment of the beam being indicated in dotted lines. Fig. 2 is a longitudinal vertical section of Fig. 1 looking toward the land side of the l l l Patented Dec. 20, 1910.

plow. Fig. 3 is a horizontal section on line 33, Fig. 2. modified construction.

Fig. 4 is a like section of a In the construction shown in Figs. 1, 2 and 3 I accomplish the change 111 position of the beam by means 0 f two levers c, c

pivoted on the frog of the plow adjacent to and slightly in rear of the rear edge of the beam.

The forwardly extending levers c, c are wedgmg 111 form, at 0 in Fig. 2 and are adapted to or forced portions of the as shown be moved between the rear edge of the plow beam and the metallic part to which it is secured. The rearwardly of the upper lever c to move the and on the s extending portion is extended and formed into a handle that can be readily grasped l l l.

levers into or out ame side of their levers are preferably connected By this construction the be moved together by secured to the plow by the bolts (1, a. clamping it tightly against the inner side of the frog which is its position when the plow is drawn by two horses.

When it is desired to change the plow to accommodate it to the draft of three horses,

the nuts on the bolts a, a

by grasping the outer end the two levers 0, c are wedgmg ends of the nuts on bolts a, beam rigidly secured. levers c, c extend only a neath the beam,

turned, forcing the levers between the beam and the part to which it a are then As the ends 0 of the is secured. The tightened and the short distance bewhen the bolts a, a are tightened the forward end of the beam will be swung to the left and will be held tightly in place. When the levers c,

0 are moved to the position shown in Fig. 3 the beam will be in the position for use To change the beam back with three horses. to its original position, the operation described, is reversed.

q I By moving the levers c, 0

a less distance, an

adjustment to a lesser degree is secured.

In Fig. which the position of the set screws (Z, (Z passing openings or eyes 0, a part of the beam.

i I have shown a construction in beam is varied by through threaded e secured to or forming The ad ustment is brought about by loosening the bolts a, a

and then turning the set screws (Z, (Z to cause the rear edge of the beam to take the position desired.

The securing of the adjusting devices to the frog to engage the rear edge of the beam or by securing them to the beam to engage the frog is of decided advantage as the landside may become broken or so worn as to necessitate its removal and the placing of a new part in its place. With my construction this is done without any disturbance of the parts for securing the beam adjustment.

IV hat I claim and desire to secure by Letters Patent is 1. In combination with the furrow forming parts of a plow, of a metallic beam secured to one of the furrow forming parts in rear of the main body of said parts, and a metallic device movably mounted adjacent to said beam and adapted to be moved into and out of position to vary the angle of the beam to the part of the plow to which it is attached.

2. In combination with the earth engaging parts of a plow, of a metallic beam secured in the hollow in rear of the said earth engaging parts against the metal forming one side of said hollow and a metallic device movably mounted adjacent to said beam and adapted to be moved into and out of position to vary the angle of the beam to the part to which it is attached.

In a plow, the combination with the furrow forming parts and a frog to which they are secured, of a metallic beam secured to said frog in rear of the earth engaging surfaces of the furrow forming parts and a metallic device movably mounted 011 one of said parts and adapted to be moved into and out of position to adjust the angular portion of the beam to vary the position of the plow in respect to the point of draft.

l. In a plow, the combination with the furrow forming devices and a frog to which they are secured, of a metallic beam secured to said frog and a metallic device movably mounted on one of said parts and adapted to be moved into and out of position between an edge of the beam and an adjacent part to vary the position of the plow in respect to the point of draft.

5. In a plow, the combination with the furrow forming parts and frog, of a metallic beam secured "to said frog and a metallic device movably mounted on said frog having wedging portions adapted to be moved into and out of position between an edge of the beam and the said frog.

(5. In a plow, the combination with the furrow forming parts and a frog, of a metal lic beam secured to said frog and levers each having a wedging portion, said levers being adapted to be turned to place the wedging portion between the rear edge of the beam and an adjacent part to vary the position of the beam.

7. In a plow, the combination with the furrow forming parts and frog, of a metallic beam secured to said frog and a movable device pivotally mounted upon said frog and adapted to be moved into a position to increase or decrease the distance between said frog and one edge of said beam.

8. In a plow the combination with the furrow forming devices and frog, of a metallic beam secured to said frog in rear of the main earth engaging surfaces of the furrow forming devices and devices movably secured to one of said parts, said devices being adapted to engage an adjacent part at two separated points to vary the angular position of the beam for the purpose of adjusting the plow with respect to the point of draft.

In testimony whereof I aflix my signature, in the presence of two witnesse.
